8 y^{3} - 125 = 0

y = \frac{5}{2}, y = - \frac{5}{4} + \frac{5 3}{4} i, y = - \frac{5}{4} - \frac{5 3}{4} i

Solution steps

8 y^{3} - 125 = 0

Move

125

to the right side

8 y^{3} = 125

Divide both sides by

8

y^{3} = \frac{125}{8}

For

x^{3} = f (a)

the solutions are

Simplify

y = \frac{5}{2}, y = - \frac{5}{4} + \frac{5 3}{4} i, y = - \frac{5}{4} - \frac{5 3}{4} i

(x + 6)^{4} = 0

4 x^{3} - 6 x^{2} + 1 = 0

x^{4} - 5 x = 0

20 u^{4} - 13 u^{2} + 2 = 0

x^{3} + 2 x^{2} + 4 x - 8 = 0
